Some factors affecting the control of proteolytic enzyme reactions on wool

Control over the modification of wool by a proteolytic enzyme was found to depend on the choice of buffer and its ionic strength, as well as on the pr evious processing history of the wool and the pH profile of the protease, I n particular, the activity towards wool of a nonspecific endoprotease (Novo zym 655L) was shown to be much greater in sodium tetraborate buffer than in ammonium sulphate buffer at the same pH and ionic strength.
